HOMGEOSOMA SENECIONIS. 225 



much more abruptly from the eleventh segment 

 forward to tbe head. The skin is smooth, but each 

 segment has four depressions, two transverse in the 

 centre, and one on each side, which, together with the 

 clearly defined segmental divisions, give it a somewhat 

 puckered appearance. 



The ground colour is dark olive-green, with a faint 

 purple tinge on the dorsal area; the head, frontal, and 

 anal plates black, in some specimens dark sienna- 

 brown; the alimentary canal, of a darker shade than 

 the ground colour, shows through as the dorsal line ; 

 but there are no perceptible subdorsal or spiracular 

 lines ; the spiracles are black. The ventral surface is 

 uniformly olive-green, some specimens showing a more 

 decidedly green tinge than others. The anterior legs 

 are of the same colour as the head, but very indis- 

 tinctly ringed with white. 



It feeds in the flower-heads of ragwort, drawing 

 together the clusters of flowers with silken webs; and 

 when full-fed forms a toughish silken cocoon. (George 

 T. Porritt, 6th July, 1886; Entom., August, 1886,

HOMCEOSOMA SINUELLA. 



Plate CLYII, fig. 6. 



Towards the end of July, 1879, Mr. W. E. Jeffrey 

 sent me five eggs in a cluster. 



The egg is of a long oval shape, apparently smooth, 

 of yellowish-white colour, and turns rather dirty a 

 little before hatching. 



They hatched on the 1st of August, and were 

 placed on the lower part of stems just above the root 

 •of Plantago lanceolata. 



These larvae were of a pale tint of drab, slightly 

 inclining to ochreous, having a dark brownish-black 

 head and plate on the second segment.
